INSIDE SHOE To a whom t may concern:

Be it known that I, JOHN HENRY Fossa subject of the Emperor of' Russia, residing in Passaic, in the county ot Passaic, inthe State of New Jersey, have invented a certain new and useful Improvement in Inside Shoes, of which the following is a specification.

My improved shoe is adapted to be used iuside of larger boots or shoes of ordinary con struction as an extra protection in cases Where the feet are to be exposed to very great cold with little exercise, as horse-car drivers and lumbermen. The shoe gives a double covering for the toes with unusual facility for yielding to match different shapes of feet and to accommodate the motions. In its most complete form I provide a loose flap, which may be arranged to lie under or over the toes as the severity of the Weather may require. When this ap is raised it makes a triple extra protection for the toes of the wearer,-two thicknesses of the shoe proper, and one thickness of the flap.

I make this shoe of thin material, having high non-conducting properties, preferably gut, limbered and perforated.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying ont the invention.

Figure 1 is a perspective view. Fig. 2 is a central longitudinal section, and Fig. 8 a transverse section.

Similar letters of reference indicate correspending parts in all the iigures where they appear.

A is an inner sole and B an outer sole, each very thin but of an ordinary form.

D', D2, are the two parts of the upper, joined together by a seam extending up and down at the heel. The peculiarities in the construction are at the front. The two portions D, D2, are separate and distinct, and lie one over the other at the toe. Except at the rear these parts D', D2, are not joined together. I will designate the overlapping portion of each part as D3. Each is joined to the solo around the Whole front of the shoe.

E is a loose Iiap attached to thesole within the shoe, so arranged that it may lie either on the surface of the in-sole with the toes over it, or may lie along the under sido of the over-lapped part D3 with the toes under it. Its length is sufficient to reach up on the instep, covering the foot further than the parts D', D2.

My shoe may be used either inside or out side of the stocking, the choice depending somewhat on the relation of the size to the foot. In either position it adds but little to the thickness of the foot-covering, but contributes greatly to the Warmth. If the Weather is very severe, the {iap E is raised and the foot inserted under it. If the Weather is more moderate, the flap E is depressed and laid on the in-sole, and the foot placed over it. Under either condition there is the double covering of the toes due to the overlapping ot' the parts D', D2 over the Whole surface D3.

The preferable material for all the parts of my shoe is gut or bladder, limbered by rolling or suitable mechanical treatment. The front portion of the shoe, especially where the material is double, should be perforated, as indicated by d, to allow the escape of perspiration. I propose to join the parts to the sole by cement, but owing to the peculiar nature ot the material I prefer with all cements with which I have experimented to employ also at each junction a line of stitching.

The shoe may serve with some success as an ordinary slipper for in-door use.

Modifications may be made without departing from the principle or sacrificing the advantages ofthe invention. I can extend or restrict the parts so that the over-lap Df1 will be Wider or narrower. Parts of the invention can be used without the whole. I can omit the flap E.

I claim as my invention- 1. In a shoe of thin material adapted for use inside of an ordinary shoe or boot, the two parts of the upper held separate and dis tnct at the front and attached each independently to the sole, with a. portion at ho In testimony that I claim the invention toe overlapped, as herein specified. above set forth I amx my signature in pres- 2.
